Newbee beginner problem - widgets don't show propperly
Message 1 in thread
Hello
I'm trying to write a simple widget to find out why they don't show
correctly.
Simple::Simple (QMainWindow *parent, const char *name)
: QMainWindow (parent, name)
{
QGrid *grid = new QGrid (4, this, "grid");
QPushButton *one = new QPushButton ("&one", grid, "one");
QPushButton *two = new QPushButton ("&two", grid, "two");
QPushButton *three = new QPushButton ("t&hree", grid, "three");
QPushButton *quit = new QPushButton ("&Quit", grid, "quit");
connect (quit, SIGNAL (clicked ()), qApp, SLOT (quit()));
}
Only button one and half of button two is visable! What have I not
understood ..?..
pls help

How one uses QMainWindow. You don't create a layout on a QMainWindow,
rather you create it on a plain simple QWidget and then use
setCentralWidget to set the central widget of the mainwindow to this
widget.
Or if you don't need menubar,toolbar and statusbar just use a plain
QWidget as base class.

Just look for a second at the code... I'm sure it's Qt 3.x
After creating a grid object try calling setLayout(grid);

Hope this will help...
Simple::Simple (QMainWindow *parent, const char *name)
: QMainWindow (parent, name)
{
myControlLayout *myLayout = new myControlLayout(this);
setCentralWidget(myLayout);
OR
setCentralWidget(new myControlLayout(this));
}
// this is your layout manager
myControlLayout::myControlLayout(QWidget *parent)
: QWidget(parent) {
QVBoxLayout *vbl = new QVBoxLayout; // you can use other
Q_CHECK_PTR(vbl);
setLayout(vbl);
QPushButton *one = new QPushButton ("&one", grid, "one");
QPushButton *two = new QPushButton ("&two", grid, "two");
QPushButton *three = new QPushButton ("t&hree", grid, "three");
QPushButton *quit = new QPushButton ("&Quit", grid, "quit");
connect (quit, SIGNAL (clicked ()), qApp, SLOT (quit()));
vbl->addWidget(one);
vbl->addWidget(two);
vbl->addWidget(three);
vbl->addWidget(quit);
OR
vbl->addWidget(new QPushButton ("&Good By", grid, "By By..."));
show();
}
